Measuring Software Systems’ Performance

A cost-effective way to extend applications is to use distributed computing. There are two main components of the network architecture: the server and the client. The network can have thousands of servers and tens of thousands of personal desktop computers, laptops, wireless and pocket clients, each of which connects to servers over a network. Client / server systems are some of the most widely used in the industry, and a huge part of the ongoing testing is associated with client / server / network environments. Security requirements testing and accessibility requirements testing are more about system testing rather than software app testing. For databases, you may need to create instances, since an application running in the same city / country should receive the same results when the database is requested, as the same application that is running in another city / country.

Client / server application testing requires a deep understanding of the software architecture, including data warehouse servers, characteristics of information pathways and load balancing servers. In most cases, for testing to be successful, it is crucial to define test data. Quality assurance consulting service is designed to provide you with award-winning quality assurance and testing solutions to ensure success of any development project.

While testing applications which are intensively used for data exchange, it is required to resort to 2 approaches such as the use of test templates and randomized data flows. If the main purpose of testing is to check the reliability of the communication path, then template-based testing can be used. It is much easier to detect distortion in a repeating graphic pattern than to view a printout with data values ​​to see if there is any error in them. Electronics engineers similarly use oscilloscopes, viewing oscillograms of test frequency signals to verify the correct functioning of the connection or process. Testers should use this technology in the self-test of the communication path during the initial start-up of the system. As soon as the communication path passes the self-test at the initial start, it is possible to transmit a previously known set of transaction data, which will verify the correctness of the transaction and the performance of the transaction processor. The output data stored in output records or log files can be automatically compared with the expected results.
